Multiply base x height then divide by 2 if finding surface are if finding volume multiple base x height x width and divide by 3
Answer:
The quadratic equation is X^2 -26X +144=0
Step-by-step explanation:
You can do it shortly by using the formula
X^2-(sum)x+ product
which will give you
X^2- (8+18)x+8×18
=X^2 -26x +144
=X^2 -8x-18x + 144
=(X^2-8x)(-18x+144)
=X(X-8)-18(x-8)=0
(X-18)(X-8)=0
X-18=0 And X-8=0
X=18 X=8
. Therefore the quadratic equation is X^2 -26X +144
Answer:

Step-by-step explanation:
Replace the value of x with 8:

20.00 -7.45
12.55 Is the result
The letter o? I'm not exactly sure but I think that's right :)
